Why cripple modern machinery and cutting tools with outdated mounting hardware?
Conventional sleeves & bushings = weak links in I.D. turning operations.
From tool tip to machine bed: every connection matters!
ENA boring bar sleeves for small to medium-size bars present a radical departure from standard decades-old designs. Upgrade now to enjoy:
​
-
Increased Rigidity and Chatter Resistance. Special profiles stabilize:
-
the bar inside the sleeve.
-
the sleeve inside the holder.​
-
​​
-
Better Coolant Delivery. A simple and robust sealing system sends coolant through the hole or around the bar (you choose) rather than spraying in all directions.​
​​
-
Easier Set-Up. A wide and un-interrupted indication band facilitates fast and precise alignment of the bar and spindle centerlines, essential for optimal performance.​
​​
-
Greater Durability. Bearing-grade alloy steel fully case-hardened to 60HRC resists scratches, dings and set-screw gouges much better than typical soft or semi-hard sleeve materials.
​​
These benefits are achieved without resorting to restrictive, sensitive and expensive proprietary bar mounting systems. No special holders, tools or procedures are required.
Same M.O. --> Better Results
Works Better + Lasts Longer = Superior ROI...
...and a smaller carbon footprint.
Ideal for chatter-prone I.D. turning operations such as:
-
Hard turning.
-
Boring of tough alloys.
-
Threading & grooving.
-
High bar length/diameter ratios.
​
Do you frequently experience issues with internal turning operations?
Before dismissing your premium machinery or cutting tools as incapable, or to simply accelerate existing operations, please be sure to consider the connection between bars and turret (or B-axis head).
While no boring system is truly "chatter-proof", better sleeves allow cutting tools and machinery to run closer to their full performance potential. Anti-chatter remedies such as “spindle speed oscillation” are all the more effective when the entire insert-to-bed chain is mechanically stable. Controlled coolant delivery, even for bars with flats, is also a welcome development.​​
Adopt early & gain an advantage:
Use quality holders with next-generation ENA sleeves.
